CUSPIDOR.

Specification of Letters Patent.

Patented Mar. 16, 1915.,

Application filed April 3, 1914. Serial No. 829,316.

T0 allen/10m t may concern Be it known that I, SPYRos FRAGoULIs, a subject of the King of Greece, residing at Boston, inthe county of Su'olk and State of Massachusetts, have invented new and useful mprovements in Cuspidors, of which the following is a specification.

This invention relates to improvements in cuspidors.

More particularly it relates to vessels, of the sort described, having means for an automatic wide opening, combined with a tight and sanitary closure; having an eX- terior aspect which is or may be ornamental, or at least inoffensive; external means for opening the vessel in ordinary use, and easy opportunity for thoroughly cleaning all parts.

The invention may be embodied in various forms, and so the patent is not to be deemed restricted to the particular embodiment here illustrated, but the drawings illustrate one form which is at present believed best, and it is intended that the patent shall cover in the appended claims whatever' features of patentable novelty eX- ist in the invention.

In the accompanying drawings: Figure 1 is an elevation in medial section'. Fig. 2 is an elevation, with a part of the exterior wall broken away to show the interior vessel, viewed perpendicularly to the plane of Fig. 1. Fig. 3 is an elevation of a detail as seen by a section on the line 3-3 of F ig. 1.

Referring to the drawing, 10 indicates a vessel in the general form of a bowl, which may be of porcelain or other material adapted to receive the sputum; 11 is a frame adapted to support it, being held on a standard 12 which, in turn, is mounted on a base 13. A cylindrical casing 14, resting removably within this base, is covered by a removable top 15 having a hole 16 over the top of the vessel 10. The parts last mentioned may be of any suitable shape and aspect. The form shown in the drawing is more or less spherical with a plane aperture in the middle through which is visible the spherical cover 17 of the vessel within. A ring of rubber or other suitable material 18 surrounds the top of the vessel and makes a tight packing between it and the under side of the cover 17. The mechanism by which the cover is shifted between this and its opened position at the side of the vessel within the casing 14, is one feature of the invention. The said cover 17 is in the form of an arch, or inverted yoke, being supported by arms on which are two axles or pins 19, one at each side which are rigidly fastened to it and which project through the supporting standard 11, outside of which they carry small spur pinions 2O rigidly attached. A convenient method of manufacture is to make each pin integral with its spur pinion. The pinions are adapted to engage racks, 21, at the ends of a. yoke shaped piece 22 which rises and spreads under the standard 11 and vessel 10 from a central boss or stub 23 extending through the base 13. This has enough of a bearing in the base to be able to slide up and down therein and maintain itself plumb while doing so. Vllithin the boss is a spring 24C whose upper end bears against the rigid standard 12, pressing downward on the yoke 22, but which will yield to allow that yoke to move upward. Means to lift the yoke are provided, in the form of a series of levers 25, pivoted under the base and projecting radially out to points 26 where they engage aring 27 surrounding the base. This ring may be depressed by a person touching it at any point, and when it is so depressed the levers 25 rise at their inner ends and so lift the boss 23, yoke 22 and racks 21.

When the cover 17 is in its closed position the pinion 2O is engaged with the upper portion of the rack 21 illustrated in Fig. 1. The pin 19 with which this pinion is integral, or otherwise made rigid, has an intermediate portion 19 which is reduced from cylindrical to flat cross section, so as to fit non-rotatably into the lower part of the slot, the peculiar shape of which is seen in Fig. 2 marked 29. When so positioned, the pin 19 cannot rotate and so the pinion cannot rotate, because of the fit of the intermediate portion 19 in the slot 29. Consequently, when the rack 21 is pushed upward it raises the pinion bodily, not being able to rotate it; and it carries upward with it the cover 17, until the intermediate portion 19 of the pin reaches the upper end of the slot 29, which, as seen in Fig. 3, is circular and of the same diameter as the said intermediate portion 19 was before it was cut down to the flat shape illustrated in Fig. 3. As soon as the part 19 reaches this portion of the slot 29 it no longer is restrained from rotating. Furthermore it cannot rise higher. Consequently the pinion 2O begins to rotate, and with it the pin 19 and the cover 1'7, the latter swinging downward to the side as illustrated in Fig. 2, until the pinion 2O reaches the lower end of the rack 21.` The vessel 10 is then completely uncovered. When pressure on the ring 27 is released, the unbalanced weight of the yoke 22, combined with the power of the spring 211, presses the rack 21 downward. The first result of this is to rotate the ypinion 20, carrying the cover 17 up to a position over the top of the vessel 10 and turning the pin 19 until its intermediate portion occupies a position in the upper part of the slot 29 just above the position illustrated in Fig. 3, with its edge toward the lower part of the slot. Having reached that position, and the pinion 20 having at the same time reached the limit of its travel on the rack 21, it drops into that slot; and the yoke 22 and cover 17 descend together until their downward motion is arrested by the under side of the cover impinging on the rubber packing ring 18. The weight of the parts and the pressure of the spring thereafter maintain the cover in that position, sealing tightly the tog of the vessel.

For the proper guidance and control of the pinions 20, and to keep the cover 17 central by keeping the pins 19 central, it is convenient to provide a slot 30 to confine the pinions in the yoke 22, thus relieving some of the wear on the pins and slots 19, 29. rlhe rack 21 forms one side of this slot; and the slot is made of such width that the pinion is close to its other side at the same time; and of such length that the ends of the rack at the positions shown respectively in Fig. 2, where the cover is turned far enough to open the vessel, and in Fig. 1, where the cover has been turned upwardl far enough to be centrally over the opening lwhich it is to close. This slot, with the rack along one side of its interior, is conveniently made as shown in Fig. 2 by providing a recess in the upstandingend of the yoke 32. This recess forms both ends and one side of the slot; and then' an additional piece including the rack is attached to form the other side of the slot 30, making it complete.

In operation,V the depression of the ring 27 first raises the cover 17 vertically upward enoughso that it can clear the top of the vessel; and then swings it over the the slot arrest the travel of the pinion onv side. Release of the ring 2 7 causes the cover 17 to swing to, and stop at, a position vertically over the vessel, and then to descend upon it, sealing it tightly. The top 15 and the side Walls 14 are removable by simply lifting; thus exposing the vessel 10 and permitting it to be removed; and all parts are thus readily accessible for cleansing.

I claim as my invention:

1. The combination of a vessel; a cover therefor, having arms which support it and depend beside the vessel; axles fast on the arms, besides the vessel; bearings therefor, in which the axles may rotate; said axles being non-circular, and there being recesses extending said bearings vertically downward as slots into which the axles can descend non-rotatably; and actuating means engaging said axles eccentrically whereby a continuous movement of the actuating means lifts them from their slots and then rotates them in their bearings.

2. The combination of a vessel; a cover therefor, having arms which support it and depend beside the vessel; axles fast on the arms, beside the vessel; bearings therefor, in which the axles may rotate; said axles being non-circular, and there being recesses extending said bearings vertically downward as slots into which the axles can descend non-rotatably; pinions fast on the axles; racks engaging them, and movable vertically; and actuating means adapted to raise the racks, whereby the pinions are rst elevated, without rotation, and then are rotated without elevation.

3. A cuspidor comprising a standard adapted to hold` a vessel; said vessel, adapted to receive sputiun; a cover therefor, havV ing arms which support it and depend beside the vessel; axles fast on theV arms beside the vessel; pinions fast on the axles; yokes passing under said vessel, adapted to slide up and down on said standard, and having grooves in which said pinions lit, and racks within the grooves engaging the pinions; means guiding the rotation and elevation of said axles, whereby their rotation is prevented during the initial elevation of the rack, permitted after a predetermined elevation of the axles, and stopped after continuing to a predetermineddegree.
